I installed RSpec in an application, and when I ran the test code, I got an error. No matter how many times I review it, there should be no problem with the settings and description, but why doesn't it work? ..
** The cause was a gem called "spring". ** ** I entered the following command in the app directory and ran the test code again and it worked fine. Was good.
[email protected] myApp % spring stop Spring stopped.← OK if this notation appears
By the way, don't worry, this spring will restart automatically when you enter the rails command.
Simply put, it's like a rails cache. It is installed by default in Gemfile when rails new.
In this case, the cache before the introduction of RSpec happens to remain, If you execute the test code in that state, it seems that you get an error saying "RSpec cannot be used".
By the way, to check the status of spring, you can check it like this.
[email protected] myApp % spring status Spring is running: 97404 spring server | myApp | started 10 secs ago 97405 spring app | myApp | started 10 secs ago | development mode
If you enter in the order of
spring stop →
rails c → ʻexit
→spring status`, it will look like this.
[email protected] myApp % spring stop Spring stopped. [email protected] myApp % rails c Running via Spring preloader in process 97418 Loading development environment (Rails 22.214.171.124) irb(main):001:0> exit [email protected] myApp % spring status Spring is running: 97404 spring server | myApp | started 10 secs ago 97405 spring app | myApp | started 10 secs ago | development mode

I wondered if I could stop it with the kill command, but I couldn't stop it because it was restored immediately.
After all it seems better to move to the corresponding directory and obediently
